What can one say about a document like this? It's largely for professionals in the medical industry. There is a text on page 37 though, that makes clear that the PCR test isn't reliable 100%
What I've found on page 37 is this:
CDC/DDID/NCIRD/ Division of Viral Diseases Effective: 07/13/2020
The optimum types of specimens to collect, and
during the course of infection, when these specimens are most likely to contain levels of viral RNA that can be readily detected.
*(Detection of viral RNA may not indicate the presence of an infectious virus or that 2019 nCoV is the causative agent for clinical symptoms.)*
The performance of this test has not been established for monitoring treatment of 2019 nCoV infection.
The performance of this test has not been established for the screening of blood or blood products or the presence of 2019 nCoV.
*(This test cannot rule out diseases caused by other bacterial or viral pathogens.)*
